关于学校禁止手机使用的最佳研究
一项利用全国范围数据进行的最新研究评估了“可锁手机袋”限制学生使用手机的效果。
研究发现，采用可锁手机袋显著减少了学生使用手机的行为，但短期内可能会增加纪律问题并降低学生的幸福感。
随着时间的推移，这些负面影响逐渐消失，学生的幸福感甚至有所提升。
学业成绩方面，标准化考试分数的影响总体接近于零，高中可能略有积极影响（尤其在数学方面），而初中则可能出现轻微负面影响。
该研究没有发现手机禁令对出勤率、上课注意力或网络欺凌的影响。

Schools across the U.S. have sharply restricted student use of phones during the school day. We evaluate one type of restriction—lockable phone pouches—using nationwide data combining large-scale surveys, GPS pings, standardized test scores, and school administrative records, along with sales records from the largest pouch provider. Using a staggered difference-in-differences design, we find that pouch adoption substantially reduces phone use as measured by GPS pings and teacher reports. In the first year after adoption, disciplinary incidents increase and student subjective well-being falls, consistent with short-term disruption. However, effects on well-being become positive in later years and disciplinary effects fade. For academic achievement, average effects on test scores are consistently close to zero. High schools see modest positive effects, particularly in math, while middle schools see small negative effects. We find little evidence of effects on school attendance, self-reported classroom attention, or perceived online bullying.
In sum, it is fine to want to run a school that way, but do not expect huge educational gains, if any. The evidence on this is accumulating, but many seem unable to accept the results. In any case it is not worthy of a major moral crusade.
Here is the NBER working paper, with top-tier researchers involved I might add, namely .
